MOLD.

Patented Sept. 30,1913.

Application filed July '27, 1912. Serial No. "711,939.

To all whom it may concern:

Be it known that I, AUGUST SoHLIoHT, a

citizen of the United States, residing at Canto which it appertains tomake and use the My invention relates to molds, and more particularly tothat class of molds for forming culverts. I

The object of my invention is, to provide a sectional mold comprising aplurality of adjust-able parts, whereby culvertsof different sizes maybe formed with one and the same mold. 7

Another object is to provide a mold of this character with wing boxesfor forming the I Other objects and end .walls or wings for the culvertintegral with the main portion thereof.

advantages will be herepointed out in the speciinafter set forth andfication and claim.

In the accompanying drawings which form a part of this application,

constructed in accordance with my invention. Fig. 2 is an end viewthereof showing the wing box removed. Fi 3 is a frag inentary sectionalview on t e line 3-3 of Fig. 1, and, Fig. 4 is a fragmentary elevationof the inner face of' t-hejside walls of the mold showing a lockingmeans for retaining the sections thereof in alinement.

Referring more particularly to the drawings, inwhich similar referencecharacters denote corresponding parts throughout the several views, 1indicates the side walls of the structure,'which walls are preferablyformed in sections, as shown in Fig. 2, two of the sections of each wallhaving their abutting surfaces beveled, as shown at ,2, to provide a keyblock 3 by means of which the walls may be readily takendown after aculvert has been formed thereover. The ends of the sections are providedwith alined slots 4-, withinwhich are positioned bolt-s or rods 5 forretaining the sections in perfect alinement. In some instances, however,where culverts of engaged beneath each of the disposed within the 4Figure 1 is Y va perspective View of a moldfor a culvert great lengthare built it is neces sary to provide means for retaining the sectionsin alinement adjacent the center there-' 0f,in which instance, I provideeach of the sections with a bracket arm 6*, except the key block 3 andthe bottom section 2 and to the latter is pivoted adapted, when thesections are set up, to be bracket arms 6*. The walls are properly heldin spaced relation by means of braces 2*, comprising parallel end piecessecured upon the upper surface of the upper section of each wall, andextending longitudinally thereof, is an angle iron 6. Positioned betweenthe side walls and havingtheir longitudinal edges angle iron 6 are theoverlapped top sections 7. For forming the end walls or wings of theculvert, I provide wing boxes 8, comprising side Walls 9 se cured at theends of the walls 1 by means ofpivoted locking arms 10 having nuts 11upon their outer ends, and secured to the top sections by means ofthreaded lugs 10 and nuts 11. The ends 12 and sides 15 of the wing boxesare formed integral and are attached to the side walls 9 by the threadedlugs and nuts. As clearly shown, the central portion of the wall 9between the walls 1 and the top sections 7 of the culvert mold is cutaway as shown at 9?, whereby the water may flow thereunder while aculvert is being constructed. The side wall 15 is provided with anaperture 12*, conforming inshape to the the locking arm 8 shape-of thewalls 1 and top sections 7 but is of greater size than the latter.

By the construct-ion ofmold as herein disclosed, it will be obvious thatwhen the cement is poured upon the bcdy thereof and the wing boxesfilled, the body portion of the culvert of will be formed integral, theresulting structure being extremely rigid; i

To take down the mold the first step is to remove the wing boxes byloosening the nuts 11 and 11*, when the bolts 5 may be readily removed.After the braces 2 have been removed, the walls and apertured topsections loosening the key block 3.

' What I claim'is:

The combination with a culvert mold having sectional side walls and atop, the ends may be quickly disassembled by merely of the sections of,heside walls being slotted and tlie'wings or end walls therevertically, a rod positioned in theslots of. In testimony whereof I havesigned my each wall; of a two-part Wing mold having name to thisspecification in the presence of a side adapted to' be secured againstthe ends twosubscribing witnesses. of the Walls to retain'the rods 1nposition and AUGUST SCI-ILICHT. 5 another side formed integralwith theends, Witnesses:
